Abstract

The invention relates to a manufacturing method of an aluminium alloy workpiece with a complex inner cavity body, comprising the following steps of: firstly analyzing a real object or design diagram of the to-be-manufactured aluminium alloy workpiece with the complex inner cavity body, then drawing a three-dimensional diagram of the aluminium alloy workpiece, carrying out equidistant or non-equidistant virtual segmentation on the aluminium alloy workpiece along the direction of the height axis of the aluminium alloy workpiece so as to obtain continuous virtual slices, numbering the virtual slices according to the sequence, carrying out facsimile reproduction respectively on the virtual slices on prepared processing plates according to the numbers, then assembling the processing plates after being processed according to the numbers of the corresponding virtual slices, then conveying the processing plates which are assembled and firmly pressed into a vacuum brazing furnace for vacuum brazing, finally carrying out finishing and clearing on assembled bodies after vacuum brazing, passing the qualification inspection, and then obtaining the to-be-manufactured aluminium alloy workpiece. The design not only is suitable for manufacturing the aluminium alloy workpiece with the complex inner cavity body, and has lower manufacturing difficulty, but also has higher accuracy and higher production efficiency and can ensure consistency of materials.

Description

technical field [0001] The invention relates to a method for manufacturing an aluminum alloy workpiece, in particular to a method for manufacturing an aluminum alloy workpiece with a complex inner cavity, and is particularly suitable for the manufacture of an aluminum alloy workpiece whose inner cavity is a closed or semi-closed multi-layer staggered structure . Background technique [0002] At present, in the processing of existing aluminum alloy workpieces with complex inner cavity structures, especially in the processing of realizing closed or semi-closed multi-layer interlaced structures inside the workpiece, if the traditional machining method is adopted, it will be affected by the processing technology and cutting tools. It is difficult to realize because of the limitation, and the precision is low; if aluminum alloy die-casting, pouring and other methods are used, it will be difficult to realize due to the difficulty of mold manufacturing. [0003] The Chinese patent...
